Cokin P Series Hard-Edge Graduated Blue 0.5 Filter (1.6-Stop)

The Cokin P Series Hard-Edge Graduated Blue 0.5 Filter provides a 1.6-stop graduated color effect, gradually tinting a portion of the frame blue while leaving the remainder of the image unaffected, giving photographers a creative in-camera tool for enhancing or introducing color into otherwise flat or overcast skies. Designed for use with Cokin’s P Series filter holder system, this rectangular filter slides into a compatible holder attached to the front of a lens.

Graduated color filters like this one are commonly used in landscape photography to add a more dramatic or saturated blue tone to a dull, gray, or washed-out sky, giving images a punchier, more visually appealing atmosphere without needing extensive color correction in post-processing. This effect can be particularly useful in overcast conditions where the natural sky lacks the vibrant blue tones photographers often want in their landscape compositions.

The hard-edge transition on this filter creates a more defined, distinct line between the tinted and untinted portions of the frame, making it best suited for scenes with a flat, unobstructed horizon line, such as seascapes or open landscapes, where a clean separation between sky and foreground allows the graduated effect to blend naturally into the composition.

As part of the widely adopted Cokin P Series system, this filter is compatible with a broad range of Cokin P-series holders and adapter rings, giving photographers flexibility to use the same filter across multiple lenses simply by swapping the adapter ring rather than purchasing filters for each individual lens thread size. Its rectangular shape also allows the filter to be slid up or down within the holder, giving photographers precise control over where the graduated color transition falls within the frame.
